Stability is an important underlying assumption in any form of assessment-supported decision-making. Since early years development is frequently described as unstable, the concept plays a central role in the discussion surrounding early years assessment.

The current study aims to examine the extent to which (change in) self-control and (change in) delinquent attitudes relate to (change in) time spent in criminogenic settings, and the…

In addition, the roles of (1) linguistic knowledge, (2) metacognitive knowledge, and (3) linguistic fluency in predicting both the level and development of writing…

Measures of verbal and nonverbal IQ were collected in Dutch twin pairs at age 5, 7, 10, 12 and 18 years. The stability of both…

Tested the hypothesis that individual differences in reading ability increase over time, by assessing children, at seven occasions between kindergarten and third grade, on various measures of reading ability, reading behavior, and attitudes toward reading. Found that individual differences among children in word recognition, but not reading…

This longitudinal study examined consistency and change in human personality. Rather than studying the consistency of individual differences over time, an approach which considers only the stability of a variable at the group level and ignores differences in stability at an individual level, this study used a person-centered approach to study…
